Our company offers a "membrane nitrogen gas generation system" that utilizes air separation technology in non-low temperature conditions, using a membrane that separates nitrogen based on relative permeability by passing air through hollow fiber membranes. Unwanted components (such as oxygen) are simply released into the atmosphere, and no other waste is generated, allowing for the production of very clean and dry inert gas. Additionally, we design systems tailored to your needs, ranging from small to large capacities, with N2 purity levels from 95% to 99.9%. 【Components】 ■ Air Compressor ■ Air Treatment Unit ■ Membrane Unit *For more details, please download the PDF or feel free to contact us.

• Nitrogen Gas Generator

We handle an "Inert Gas Generating Unit" that uses an oil burner equipped with either diesel or A heavy oil to combust and produce combustion gas, which is then cooled and cleaned by a scrubber to generate clean inert gas. It can be operated via a control panel equipped in the IGG unit. Compared to inert gas systems that utilize combustion gas from auxiliary boilers, it can supply cleaner inert gas. Additionally, you can choose between two types of backflow prevention devices: a deck water seal and a double block & bleed valve. 【Components】 ■ Inert Gas Generating Unit (IGG) unit (burner, scrubber, control panel, etc.) ■ Monitor panel ■ F.O. pump unit ■ Blower ■ Oxygen analyzer ■ Control valve ■ Backflow prevention device ■ Oxygen analyzer *For more details, please download the PDF or feel free to contact us.

• Gas Generator

Our "Inert Gas System" utilizes a top-level venturi scrubber for wet dust collection and employs a packed tower with high-performance packing for desulfurization, generating clean inert gas. To prevent severe corrosion from sulfur dioxide in exhaust gases, we adopt advanced anti-corrosion designs, including the use of corrosion-resistant steel, special coatings, and rubber linings. Additionally, by equipping an optional inert gas generator, the system can serve as a source of inert gas during topping up when a small amount of inert gas is required while at sea, without the need to operate the inert gas system itself. [Optional] ■ Topping Up Inert Gas Generator *For more details, please download the PDF or feel free to contact us.

• Gas recovery/treatment equipment

We offer "automatic sprinkler systems," designed to detect fires and operate automatically, as well as "manual sprinkler systems and pressurized water spray systems," which can instantly release water into the target area by opening a valve. These systems can quickly release water into the fire compartment, contributing to accurate responses in the initial stages of a fire. 【Features】 ■ Automatic Sprinkler System - Mainly adopted in passenger ship living quarters - Operates automatically, requiring no crew operation - Emits a visible and audible alarm when activated, notifying the crew of the fire location - Operates at specified temperatures in living and operational areas ■ Manual Sprinkler System and Pressurized Water Spray System - Mainly adopted on the vehicle decks of RO-RO ships - Allows for initial firefighting by manually opening the valve in the target area *For more details, please download the PDF or feel free to contact us.

We have developed a fixed gas fire extinguishing system using the fire extinguishing agent "3M(TM) Novec(TM) 1230," which was developed by 3M Company in the United States for total flooding applications. "Novec(TM) 1230" vaporizes immediately upon release from the nozzle, achieving extinguishment through its cooling effect. Since it does not rely on suffocation for extinguishment and the extinguishing agent itself is low in toxicity, it offers high safety. The number of required cylinders is about two-thirds compared to carbon dioxide and about half compared to nitrogen gas, allowing for efficient use of space. 【Features】 ■ Vaporizes upon release from the nozzle, achieving extinguishment through cooling effect ■ Low toxicity and high safety ■ Reduction in the number of cylinders allows for efficient use of space ■ Excellent environmental characteristics ■ Short extinguishment time reduces heat damage *For more details, please download the PDF or feel free to contact us.

The FMS (Fixed Monitor System) is a helicopter deck foam firefighting system consisting of a foam monitor placed on the helideck and a fire extinguishing liquid tank unit that includes a fire extinguishing liquid pump and a foam mixing device. The extinguishing liquid uses Aqueous Film Forming Foam (AFFF), which is effective for extinguishing aircraft fuel fires. This system, which is generally operated manually, employs a self-oscillation mechanism that automatically rotates the monitor left and right at a pre-set angle, releasing low-expansion foam over a designated area, allowing for remote start and stop operations. 【Components】 ■ Foam Monitor ■ Fire Extinguishing Liquid Tank Unit (including fire extinguishing liquid pump and foam mixing device) *For more details, please download the PDF or feel free to contact us.

• Other safety and hygiene products

Our company offers the "Deck Foam Fire Extinguishing System," which utilizes the jet action of water flow to vigorously mix foam concentrate and seawater within the piping, resulting in foam that incorporates air for fire extinguishing. The foam generation method used in this system, "Air Foam," excels in fire resistance and oil resistance compared to chemical foam (foam generated by chemical reactions) and has the characteristic of foaming without issues when mixed with seawater. 【Components】 ■ Firefighting liquid tank ■ Firefighting liquid pump ■ Mixing device ■ Manual valve ■ Foam monitor, etc. *For more details, please download the PDF or feel free to contact us.

• Other safety and hygiene products

Our company offers a "local fire extinguishing device" that uses safe water mist (water particles) for crew members, without the use of chemicals or gases, to extinguish fires. We conduct safety evaluation tests of water spray on electrical equipment, assess the impact of engine room ventilation on extinguishing capability, and propose methods such as the side shot method, which is suitable for extinguishing the main engine. By solving many issues during practical implementation, we have received high international recognition. Please feel free to consult us if you have any requests. 【Components】 ■ Pump unit (a unit that combines clean water pump, pump starter, and distribution valve) ■ Spray nozzle ■ Control panels ■ Clean water tank, etc. *For more details, please download the PDF or feel free to contact us.

• Other safety and hygiene products

Our company offers a safe and high-performance inside air type "high expansion foam fire extinguishing system" for engine rooms and pump rooms on ships. The foam solution (fire extinguishing liquid) primarily composed of synthetic surfactants is mixed with seawater (or fresh water) and sprayed onto a metal foaming net, creating foam that performs fire extinguishing operations through cooling and smothering effects. Thanks to the various stabilizers contained in the fire extinguishing liquid, it has strong fire resistance and can effectively extinguish a wide range of fires, including oil fires such as gasoline, naphtha, heavy oil, and light oil, as well as fires involving wood and fabric. 【Components】 ■ Fire extinguishing liquid tank ■ Fire extinguishing liquid pump ■ Mixing device ■ Manual/automatic valve ■ Foam generator ■ Control panel, etc. *For more details, please download the PDF or feel free to contact us.

We handle the marine exhaust gas cleaning system from Clean Marine, which can process all exhaust gases (M/E, A/E, Boiler) with a single scrubber. It flexibly responds to variations in allowable back pressure due to load fluctuations in diesel engines, making it a cost-effective system. 【Features】 ■ Zero back pressure "Allstream-EGCS" ■ NaOH assist method that is not dependent on water quality ■ High-efficiency cyclone system *For more details, please download the PDF or contact us.
